Key & Compass presents:
Excelsior
by Arthur DiBianca

Excelsior is a Z-machine interactive fiction game written with Inform 7 and is © 2014 by Arthur DiBianca. It was an entry in IF Comp 2014 where it took 35th place.

In this generic puzzlefest that uses a minimalist command set, you play as someone who finds and explores a very tall tower in a forest. There's no story here. Just solve the puzzles and reach the roof to win.

This solution is by David Welbourn, and is based on Release 1 of the game.

SPOILERS AHEAD. Reading a walkthrough prematurely can sometimes diminish one's enjoyment of an interactive fiction game. Please make an honest effort to play the game before reading this walkthrough.

Forest

This game uses a limited set of commands.

> help.

> x trees. e. n.

The Tower

> x tower. x birds.

There's no visible entrance, so walk around the tower clockwise:

> w. n. e. s.

The Tower

One brick is now black. You must try to use the brick before you can walk through the wall.

> x black brick. use it. (Hand passes through it.)

> n.

Inside the Tower (First Level)

The first section of the game is about black cubes. There's a black cube on each of the first three levels of the tower, and you need to obtain all three to unlock a gate on Third Level.

> x lamps. x pedestal.

> x cube. use cube. (Taken, but grinding sound.)

> x cube. use cube. s.

South Corridor (Second Level)

> x sphere. use sphere. w. d.

Inside the Tower (First Level)

Keep the stairs usable by replacing the cube with the sphere.

> use cube. use sphere on pedestal.

Central Chamber (Second Level)

> x ladder. u.

Third Level (Third Level)

> x door. x holes. (Three square holes are empty.)

> use cube on holes.

> use cube on holes.

With three cubes in the holes, the door opens.

> n. u. s.

Statue Chamber (Fourth Level)

Now you're looking for gold coins. There's a gold coin on each level from Fourth to Ninth, and you need four of those six coins to unlock a gate on the Ninth Level.

> x gate. x statue. x words. (can't read them)

> use statue. (You get onto the plinth.)

> use hand. (You obtain a gold coin!)

> x coin. use statue. (You get off.)

> x door. use door. n.

Carpeted Hall (Fifth Level)

> x carpet. n.

North End of Hall (Fifth Level)

The doors to the east and west are locked and you never find a key for them, so you may ignore them.

Closet (Fifth Level)

> x panel. use panel. (Lever revealed.)

> x lever. (in up position)

If you use the lever and wait many times, you'll learn that the lever stays down for 13 turns, then flips back up again. That suggests you'll need to use the lever and go somewhere 11 or 12 steps distant from here and do something critical there before the lever flips up.

However, you haven't seen the place that this lever is for yet, so come back to this later.

> e. s. u. n.

North Intersection (Sixth Level)

On this level, black arrows lead towards the way up to the next level, red arrows lead back to the level below, and white arrows lead to ends of corridors where there may be something interesting (or not).

So, alternate between white and black arrows to see everything on this level.

Minor Gallery (Seventh Level)

I assume the paintings are a tribute to Myst, maybe?

> x paintings. w. w.

Guarded Room (Seventh Level)

As you enter, an alarm bell rings and the box lid shuts. The alarm won't stop until you leave.

> x table. x box. x alarm.

This is what the closet's lever is for, to turn this alarm system off. Head back to the closet:

Closet (Fifth Level)

It should go without saying that the bedroom door should be left open before using this lever. You don't want to waste a turn opening a door.

> use lever.

Now race to the Guarded Room:

> e. s. u. n. w. s. e. e. u. w. w.

Guarded Room (Seventh Level)

You have two turns to look in the box and take what's there before the box closes.

East Chamber (Eighth Level)

This room is critical to solving this level's puzzle. The circle is mean to represent opening the north gate, and the X is meant to represent closing the west gate.

> x west. (black X above gate)

> x north. (black circle above gate)

> use north. (It opens; west closes.)

> use west. (It opens; north closes.)

> use west. (It closes; north opens!)

The gates are now in a different state where closing the open gate opens another gate. Now it's just a matter of entering open gates and closing them behind you.

South Chamber (Ninth Level)

This level is basically a game of rearranging coins of different weights until you can obtain yet another gold coin. The first step is to replace the white coin with the red coin.

> use white coin. (Taken, but a gate blocks your exit.)

> use red coin on hand. (The gate slides open.)

> n. n.

North Chamber (Ninth Level)

Now replace the black coin with the white coin.

East Chamber (Ninth Level)

Now replace the gold coin with the black coin.

> use gold coin. (Taken, but a gate blocks your exit.)

Checkered Chamber (Ninth Level)

Insert four gold coins. By the way, the red, white, and black coins are too wide for the slot.

> use gold on slot. use gold on slot.

> use gold on slot. use gold on slot.

The slot is replaced with a keyhole.

> use key on keyhole. (Unlocked.)

West Chamber (Ninth Level)

CAUTION: The platform is a one-way trip up. If you didn't find all six gold coins, this is your last chance to go back and find them.

> use platform. (You're lifted up to...)

Fountain Rotunda (Tenth Level)

From here on up, the theme is water and levers. There's a lever on each level from Tenth to Sixteenth, and you need to use five of those seven levers to unlock a gate on the Sixteenth Level.

You can now use the rod to change the water flow from the west side of the tower to the east side, and vice-versa. You can never get the rod back to use somewhere else.

Leave the water flowing east to see how the rooms below have all changed.

> x machine. (You now see a lever underneath the western spout. It must have been hidden by the water.)

> use lever. n.

Five Lights (Sixteenth Level)

One light is lit. Obviously, you need to push at least five levers to unlock this door.

But if you're trying for a perfect game, you want to push all seven levers. There's a lever on every level from Tenth to Sixteenth.

> s. d. n. w.

Pool Chamber (Fifteenth Level)

The pool is now a square hole.

> x hole. x rungs. d. s. u.

Vat Room (Fifteenth Level)

> x portcullis. x vat. (Note the drain.)

> x drain. x spout.

Obviously, west-flowing water fills the vat and opens the portcullis, but you can't get here unless the water flow is east!

> d. n. u. e. d.

Northeast Quarter (Fourteenth Level)

The basins have running water now.

Ring of Fire (Fourteenth Level)

With water flowing in the groove, the fire is gone and you now see a pedestal.

> n. d. s.

Square Room (Thirteenth Level)

Wait here at least four turns to observe the frame and gate behavior while the water flow is east.

> z. z. z. z.

The squares in the frame are cycling RED WHITE BLACK GRAY, and the gate tries to open when the square is black, but it's never open far enough for you to get past it.

This means you must switch the flow to west when the square is black. Awkward! Leave this puzzle for last; it's rather sadistic.

Room with Two Stairs (Eleventh Level)

Water is flooding the upper stairway into the drain. You can't get to the Apparatus rooms while the water flow is east.

Fountain Rotunda (Tenth Level)

The fountain is having trouble staying full. Examine the basin over and over again. When it's empty, you see a metal lever.

Return to the waterwheel:

Waterwheel (Eleventh Level)

Now that the waterwheel is turning, action is happening in the southern doorway. There's actually a large rotating turntable in there, divided into three triangular rooms and a walled-off triangular area.

Timing is important if you're trying to get into a particular triangular room.

> z. (Repeat waiting until a wall blocks the frame.)

> use leather. x it. z.

Quickly go north, then south into the third triangular room:

(Third) Triangular Room (Eleventh Level)

Note that while you can just take the chain yourself to stop the rotation, you can't reach the lever at the same time. That's why you need the gnome here.

Return to the Vat Room quickly, pausing only at the Pool Chamber so it has time to drain:

A gap is revealed if and only if some water is trying to use the drain but can't, so it's using the gap instead.

Five lights are lit. If you don't care about a perfect score, feel free to open the door and go to the roof now to end the game.

But for a perfect score, you must pull all seven levers.

Race to the Pump Room!

Pump Room (Sixteenth Level)

There's no more lights to light, so either trust that the gnome did its job or return to Apparatus (North) and try to use the lever yourself to prove that it's been pushed.

Go to Square Room (Thirteenth Level):

> d. n. d. d. s.

Square Room (Thirteenth Level)

The first step in this puzzle is to change the water flow to west when the square in the frame here is black, so this gate stays open when you return here.

It takes five moves to go to the Pump Room from here and a sixth move to use the rod, except the cutoff is instant, so don't count that move. Remembering that the cycle here is red-white-black-gray, and counting five backwards from black... uh, you should wait until the square here is WHITE then race to the Pump Room and use the rod.

> z. (Wait repeatedly until the white square appears.)

> n. u. u. s. u.

Pump Room (Sixteenth Level)

> use rod. d. n. d. d. s.

Square Room (Thirteenth Level)

I'll assume all went well and the area in the frame is black and the gate is open.

> x frame. e.

Arrow Room (Thirteenth Level)

> save.

> x arrow. use arrow. (doesn't move)

The arrow will be pointing at one of three circles (red, white, or black) or at an empty gray spot on the wall.

If you're very lucky, the arrow is pointing at the black circle, and you can continue south, but I think the game is gimmicked so it's pointing at the red circle the first time you're in here.

The water flow controls this arrow too, but instead of changing every turn like the frame in the Square Room, it's changing every four turns. So you need to release westerly-water in multiples of four turns exactly to advance the arrow to the next circle while keeping the gate in the Square Room open too.

> w. n. u. u. s. u.

Pump Room (Sixteenth Level)

I'll assume that the arrow was pointing to the red circle.

> use rod. z. z. z. use rod.

The arrow should now be at white, and the square should be back at black. Feel free to go and check and come back here.

Do the four-turn burst of water again, as necessary, until square and arrow are both indicating black:

> use rod. z. z. z. use rod.

> d. n. d. d. s. e.

Arrow Room (Thirteenth Level)

> x arrow. (It should be pointing at black now.)

> s.

Basin Room (Thirteenth Level)

> save. x basins. x bars.

You probably want to re-examine the basins and wait for several turns to get an understanding of what's happening here. Over the course of 7 turns, the west basin fills up and empties itself. While the basin is filled up to the black line, the horizontal bars in the western doorway retract.

The basin cycle can be summarized as EMPTY-RED-RED-WHITE-WHITE-BLACK-BLACK.

Likewise, you can assume that when the water flow is east, the east basin fills, and when its water is past its black line, the vertical bars in the western doorway retract. (I assume the east basin will always be empty the first time you're in this room.)

But remember, the first two gates are only open simultaneously every 16 turns of eastern water flow.

Which means, if the east basin is initially empty, that you want to let eastern water flow for 16 turns to get it to the red line, for 16 turns more to get it to the white line, and for 16 additional turns to get it to the black line. And if you mistime any of this, you'll probably have to start this puzzle at the beginning.

Shame you can't just scoop some of the water over with your hands, eh?

Sigh. Let's do this, and I suggest saving the game whenever you're sure you've made progress.

> n. w. n. u. u. s. u.

Pump Room (Sixteenth Level)

I strongly recommend doing this in water bursts of four turns each. Personally, I think it's easier to count to four four times instead of up to sixteen, since I always mess it up when trying to wait longer.

The Roof

A gentleman in a hard hat rates your performance and shakes your hand.

*** You made it to the top! ***

Not to sound ungrateful, but I think I deserve a bit more than that. Maybe an entire sandwich, a way out of the tower, and a ride to the next town, maybe?
